Pixhawk 4 mini + Frsky R9SX telemetry on RC port

Hello guys. I have a multirotor mounting an HolybroPx4 mini (FMUv5) with Frsky R9SX linked to rc port. Now, this FMU has few tel port : TEL1 (in my case) linked to Holybro Telemtry radio; TEL4 with a FPV CAM and OSD and TEL2 obviously with GPS.

The question is: how can i get, via receiver, the telemetry info on the radio controller?
Currently i have TEL_FRSKY_CONFIG disabled. But in the option a can not find any solution in order to allow tel info to the receiver.

How figure out it? Or it is possible only via Tel port?
